My compressor is doing exactly what your is doing any ideas

Looks beautiful Jim - and sounds great!

What is the brand name of the motor?

I had the exact same problem with same motor. Not powerful enough to turn the compressor

November... December.. can't remember...

Can’t beat standard at our age.

Ck the run capacitor and start capacitor for the correct microfarads

eBay sells junk.i had the same problem with my electric motor

I had the same thing with my sandbon it was the Moter it is a Chinese piece of shit

At 1:04 I was like wow dudes about to stick a carrot in it

Next the BMW. Gremlins got in during the lay up.

Good job as always Jim Adam

Nice work Jim! Pete

Hey Jim, apart from a dickie headlight connection, all seems good to me.....🏍 Nice one Ads.

Lots of variables these days because of the cheap Chinesium products being shipped to the USA. I would bet the capacitors are weak...most of them are imported junk and only last maybe 1 to 2 years on equipment. You can put a meter on those caps and determine if they are weak. Replace them with USA made caps. Good electric motors are Leeson, Baldor and another brand I can't think of however, they are a good $400 to $600 for an application like this compressor.

i have an old sears horizonal air compressor with a 250 lb shutoff switch. i got it for free took it home plugged it in and nothing. tried flipping the lever on the side of the pressure switch still nothing. it is still sitting in my garage gathering dust. it sounds like a winter project if I can get parts.

is this just water?

I agree I think you got a defective motor you showed relieving the unloader valve so I assume when you had 40 psi in the tank your check valve isn’t allowing any pressure to flow back in other words you did check to make sure your check valve is not leaking back and causing motor to not be able to start up due to it lt maybe leaking pressure It seems like it’s leaking and no motor will be able to start back up if that check valve leaks anyway did you get it replaced and did it fix the problem ? If not seriously take out the check valve test it by blowing only one way

Good

Bad start capacitor

I suggest buying a quality American made motor.

Check valve

I had same problem with my air compressor, it had a 5” pulley on motor and after it cycled off and and like 3 times it would get really hot and humm. Had to attach an electric fan next to the pump just to help cool it down to finish my project. Later I swapped the 5” pulley to a 1 1/2” pulley and now it’s a lot more quiet but runs super slow. It won’t overheat no more but when I’m using power tools and it cycles back on it takes a good minute to shut off. I put a 4” pulley a new eBay 5hp motor and it works great the first 3-4 cycles and it also overheated, in the middle of using a da palm sander. Finally I swapped the 4” pulley to a 3” pulley and now it works perfect. Keep in mind also had to change v-belts too. Replaced the pressure switch when I first bought it so I know that was not the problem.

A pressure switch isn’t technically the unloader. Start capacitor is pooched and your in tank CV or the unloader isn’t really working. Unloading should happen automatically on powering off the motor. I guess that’s why industrial electricians are different than we electro-mechanics rotating equipment specialists (Millwrights). Too high of an oil level causing oil carryover upon unloading caused the two valves (unloader and in tank check valve) to get sticky and a few starts under those conditions failed the start capacitor. Compressor troubleshooting is a Millwright’s job.

Back to the camera Jim. You need a remote starter. Great job though.

Does the motor have a bad start capacitor, I know it has a run capacitor as well but I’m thinking that’s good.

Jim, is this a retro fit for all 1980 TCI bikes? Where can we get one?

Jim is this a new black witchcraft box to improve Iggy for XS650?

Nice work as always Jim!

Sounds healthy! Love that stand! 😎

Nice one Jim. Didn't know you had a TH-cam channel. Ads. 😃

Miss or red line on valves. Pop, Pop.

It’s not the motor it’s because you don’t have a compression release

Check Valve

thank you man, just got my first 79 and it didn't come with any keys

That switch you are flipping is the on/off switch. The unloading happen on it's own.

See Utube

i`ve been trying to find a pickup coil like the one your bike, do you have a brand name, part number, or specific bike I can use to find one?

You are a genius

Looking forward.

My xs650 has the same trigger as yours and it's the only one I've seen like mine. Do you know the brand or where I can find a replacement?

Witchcraft. Nice work Jim!

Interesting!

I've been following the thread on the Forum (just found it ) This is amazing, I always wondered if the cheap ignitions could be adapted to other bikes . Dave...NZ

What types of oil does a compressor need

Sounds good. Thinking abt getting em for my bike

How to remove a fuel tank I forgot my key

Pretty sure the motor lacks starting torque. It might be that the starter capacitor lost it's capacity, or it's a bad factory design that they didn't use a higher capacitance value cap. Still, you can improve the motor starting torque by changing it's original starting cap with a much much higher capacitance. Still the capacitor will not give it a really big starting torque and the motor may not start.

Bad check valve between pump and tank

I have a brand new DeWalt 60 gallon that does that now 3 months old used it maybe 10 times . $639.00 china POS.
